Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an air guiding device and an air conditioner. Background Technology

[0002] Currently, air conditioners on the market are often equipped with air deflectors. The direction of airflow can be adjusted by changing the rotation angle of the air deflector. However, since the air deflector also blocks the airflow while guiding it, it causes excessive air volume loss in the air conditioner. Summary of the Invention

[0003] The problem solved by this invention is that the air guide vanes in existing air conditioners cause excessive airflow loss.

[0004] To address the aforementioned problems, this invention provides an air guiding device that can reduce airflow loss in air conditioners and improve user experience.

[0005] An embodiment of the present invention provides an air guiding device applied to an air conditioner. The air guiding device is movably disposed within the air outlet duct of the air conditioner, and the air guiding device is provided with a first air guiding surface and a second air guiding surface.

[0006] The first air guide surface is used to cooperate with the lower side wall of the air outlet channel so that the second air guide surface guides the air downward;

[0007] The second air guide surface is used to cooperate with the upper side wall of the air outlet channel so that the first air guide surface guides the air upward.

[0008] The air guiding device provided in the embodiments of the present invention, in practical applications, when it is necessary to guide air downwards in heating mode to prevent hot air from rising, moves the air guiding device until the first air guiding surface mates with the lower sidewall of the air outlet channel, changing the structure of the air outlet channel so that the second air guiding surface guides air downwards; when it is necessary to guide air upwards in cooling mode to prevent cold air from sinking, moves the air guiding device until the second air guiding surface mates with the lower sidewall of the air outlet channel, changing the structure of the air outlet channel so that the first air guiding surface guides air upwards. It can be seen that the air guiding device provided in this embodiment, through the selective mating of the first and second air guiding surfaces with the upper and lower sidewalls of the air outlet channel, achieves a change in the structure of the air outlet channel, thereby changing the air guiding direction, avoiding obstruction of the air outlet, and significantly reducing airflow loss.

[0009] In an optional embodiment, the first air guiding surface and the second air guiding surface are respectively disposed on opposite sides of the air guiding device in the thickness direction.

[0010] The first and second air guide surfaces are respectively located on opposite sides of the air guide device in the thickness direction, so as to avoid obstructing the air outlet when the first or second air guide surface is in contact with the side wall of the air outlet channel.

[0011] In an optional embodiment, the first air guide surface is a convex arc surface that protrudes away from the second air guide surface.

[0012] The first air guide surface is a convex arc surface. When the second air guide surface is in conjunction with the upper side wall of the air outlet channel, the first air guide surface uses the Coanda effect to guide the cold air upward, achieving upward air guidance without obstructing the air outlet.

[0013] In an optional embodiment, the second air guide surface is a convex arc surface that protrudes away from the first air guide surface.

[0014] The second air guide surface is a convex arc surface. When the first air guide surface is in conjunction with the lower side wall of the air outlet channel, the second air guide surface uses the Coanda effect to guide the hot air downward, achieving downward air guidance without obstructing the air outlet.

[0015] In an optional embodiment, in the air outlet direction of the air outlet channel, the front and rear ends of the first air guide surface are respectively connected to the front and rear ends of the second air guide surface.

[0016] The two ends of the first air guide surface are connected to the two ends of the second air guide surface respectively. It can be seen that the cross-section of the air guide device is spindle-shaped, which can achieve a smooth transition at the change of the side wall structure of the air outlet channel, further reducing the obstruction effect on the air outlet.

[0017] An embodiment of the present invention also provides an air conditioner, including a body and an air guide device. The body is provided with an air outlet channel, and the air guide device is movably disposed within the air outlet channel. The air guide device is provided with a first air guide surface and a second air guide surface. The air guide device has a first working state in which the first air guide surface engages with the lower side wall of the air outlet channel and the second air guide surface guides air downwards, and a second working state in which the second air guide surface engages with the upper side wall of the air outlet channel and the first air guide surface guides air upwards.

[0018] In practical applications, the air conditioner provided in the embodiments of the present invention allows for the following configuration: When it is necessary to guide air downwards in heating mode to prevent hot air from rising, the air guiding device is moved to engage with the lower sidewall of the air outlet channel, changing the structure of the air outlet channel so that the second air guiding surface guides air downwards. Conversely, when it is necessary to guide air upwards in cooling mode to prevent cold air from sinking, the air guiding device is moved to engage with the lower sidewall of the air outlet channel, changing the structure of the air outlet channel so that the first air guiding surface guides air upwards. Therefore, the air guiding device provided in this embodiment, through the selective engagement of the first and second air guiding surfaces with the upper and lower sidewalls of the air outlet channel, alters the structure of the air outlet channel, thereby changing the air guiding direction, avoiding obstruction of the airflow, and significantly reducing airflow loss.

[0019] In an optional embodiment, the lower sidewall of the air outlet duct is provided with a first mating surface for fitting with the first air guide surface, and the upper sidewall of the air outlet duct is provided with a second mating surface for fitting with the second air guide surface.

[0020] In an optional embodiment, the first air guide surface is a convex arc surface that is raised away from the second air guide surface, and the first mating surface is a concave arc surface.

[0021] In an optional implementation, in the second working state, the first mating surface, the first air guide surface, and the left and right side walls of the air outlet channel form an upward-guiding cold air channel.

[0022] The first mating surface is a concave arc surface, and the first air guiding surface is a convex arc surface. The first mating surface and the first air guiding surface work together to guide the cold air upward, further improving the airflow guiding effect.

[0023] In an optional embodiment, the second air guide surface is a convex arc surface that protrudes away from the first air guide surface, and the second mating surface is a concave arc surface.

[0024] In an optional embodiment, in the first working state, the second mating surface, the second air guiding surface, and the left and right side walls of the air outlet channel form a downward-directing hot air channel.

[0025] The second mating surface is a concave arc surface, and the second air guiding surface is a convex arc surface. The second mating surface and the second air guiding surface work together to guide the hot air downwards, further improving the airflow guiding effect. Attached Figure Description

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Please see Figure 1 and Figure 2 , Figure 1 The image shown is a cross-sectional view of the air conditioner 200 provided in this embodiment in heating mode. Figure 2 for Figure 1 An enlarged schematic diagram of region A in the middle.

[0034] The air conditioner 200 provided in this embodiment includes a body 210 and an air guide device 100. The body 210 is provided with an air outlet duct 211, which is used to supply air to the room. The air guide device 100 is movably disposed in the air outlet duct 211 and can move to a first working state or a second working state within the air outlet duct 211 to cooperate with different side walls of the air outlet duct 211, thereby changing the structure of the air outlet duct 211 and thus guiding the airflow in different directions.

[0035] The air guide device 100 is provided with a first air guide surface 110 and a second air guide surface 130. The lower side wall of the air outlet channel 211 is provided with a first mating surface 213. In the first working state, the first mating surface 213 is in contact with the first air guide surface 110. The upper side wall of the air outlet channel 211 is provided with a second mating surface 215. In the second working state, the second mating surface 215 is in contact with the second air guide surface 130.

[0036] It should be noted that in this embodiment, the first air guide surface 110 and the first mating surface 213 are fitted together, and the second air guide surface 130 and the second mating surface 215 are fitted together. In other embodiments, the fitting form can be adjusted according to actual application conditions. When the first air guide surface 110 and the first mating surface 213 are fitted together, a gap may exist between them. Similarly, when the second air guide surface 130 and the second mating surface 215 are fitted together, a gap may also exist between them.

[0037] In practical applications, when the air guide device 100 moves to the point where the first air guide surface 110 is in contact with the first mating surface 213, the second air guide surface 130 forms part of the lower side wall of the air outlet channel 211, and together with the exposed second mating surface 215, it plays the role of air guidance; when the air guide device 100 moves to the point where the second air guide surface 130 is in contact with the second mating surface 215, the first air guide surface 110 forms part of the upper side wall of the air outlet channel 211, and together with the exposed first mating surface 213, it plays the role of air guidance.

[0038] In this embodiment, the first air guide surface 110 and the second air guide surface 130 are respectively disposed on opposite sides of the air guide device 100 in the thickness direction. The first air guide surface 110 is a convex arc surface that protrudes away from the second air guide surface 130, and the first mating surface 213 is a concave arc surface that is recessed in the lower side wall of the air outlet channel 211. The second air guide surface 130 is a convex arc surface that protrudes away from the first air guide surface 110, and the second mating surface 215 is a concave arc surface that is recessed in the upper side wall of the air outlet channel 211.

[0039] It is understandable that the first mating surface 213 corresponds to the shape and size of the first air guide surface 110, and the second mating surface 215 corresponds to the shape and size of the second air guide surface 130.

[0040] In fact, in heating mode, the air guide device 100 moves to the first working state, that is, the air guide device 100 moves to the point where the first air guide surface 110 is in contact with the first mating surface 213. In this state, it is equivalent to the lower side wall of the air outlet channel 211 having a convex arc-shaped second air guide surface 130 protruding, and the upper side wall of the air outlet channel 211 having a concave arc-shaped second mating surface 215 recessed. The second air guide surface 130 and the second mating surface 215, together with the left and right side walls of the air outlet channel 211, form a downward-directing hot air channel.

[0041] When the hot air flowing along the lower side wall of the air outlet channel 211 flows to the second air guide surface 130, since the second air guide surface 130 is a convex arc surface, according to the Coanda effect, the hot air is obliquely guided downward to the air outlet channel 211.

[0042] When the hot air flowing along the upper side wall of the air outlet duct 211 reaches the second mating surface 215, the flow direction of this part of the hot air gradually changes due to the concave arc surface of the second mating surface 215. Finally, it is blown out of the air outlet duct 211 at an angle, which prevents the hot air from rising immediately after being blown out of the air outlet duct 211, ensuring uniform distribution of hot air in the room and improving the user experience.

[0043] Please refer to the following: Figure 3 and Figure 4 , Figure 3 The image shown is a cross-sectional view of the air conditioner 200 provided in this embodiment in cooling mode. Figure 4 for Figure 3 A magnified view of region B in the middle.

[0044] In cooling mode, the air guide device 100 moves to the second working state, that is, the air guide device 100 moves to the point where the second air guide surface 130 is in contact with the second mating surface 215. In this state, it is equivalent to the upper side wall of the air outlet channel 211 having a convex arc-shaped first air guide surface 110 protruding, and the lower side wall of the air outlet channel 211 having a concave arc-shaped first mating surface 213 recessed. The first air guide surface 110 and the first mating surface 213, together with the left and right side walls of the air outlet channel 211, form an upward-directing cold air channel.

[0045] When the hot air flowing along the upper side wall of the air outlet channel 211 flows to the first air guide surface 110, the first air guide surface 110 is a convex arc surface. According to the Coanda effect, the hot air is guided obliquely upward to the air outlet channel 211.

[0046] When the hot air flowing along the lower side wall of the air outlet 211 reaches the first mating surface 213, the flow direction of this part of the hot air gradually changes due to the concave arc surface of the first mating surface 213. Finally, it is blown obliquely upward out of the air outlet 211, which prevents the cold air from sinking immediately after being blown out of the air outlet 211, ensuring that the cold air in the room is evenly distributed and improving the user experience.

[0047] To further reduce the obstruction effect of the air guide device 100 on the air outlet, in this embodiment, the two ends of the first air guide surface 110 are respectively connected to the two ends of the second air guide surface 130 along the length direction of the air guide device 100. The length direction of the air guide device 100 is actually the same as the extension direction of the air outlet channel 211, that is, in the air outlet direction, the two ends of the first air guide surface 110 are respectively connected to the two ends of the second air guide surface 130.

[0048] Since both the first air guide surface 110 and the second air guide surface 130 are convex arc surfaces, when the first air guide surface 110 is in contact with the first mating surface 213, the position where the first air guide surface 110 and the second air guide surface 130 are connected is aligned with the lower side wall of the air outlet channel 211, and the second air guide surface 130 and the upper side wall of the air outlet channel 211 have a smooth and tight transition; when the second air guide surface 130 is in contact with the second mating surface 215, the position where the first air guide surface 110 and the second air guide surface 130 are connected is aligned with the upper side wall of the air outlet channel 211, and the first air guide surface 110 and the lower side wall of the air outlet channel 211 have a smooth and tight transition.

[0049] It is evident that, regardless of whether it is in heating or cooling mode, the air guide device 100 does almost no obstruction of the airflow in the air outlet duct 211, which greatly reduces airflow loss and significantly improves the energy efficiency of the air conditioner 200.

[0050] The air guiding device 100 provided in this embodiment is spindle-shaped, forming a smooth airflow through the air outlet of the air conditioner 200. In other embodiments, the shapes of the first air guiding surface 110 and the second air guiding surface 130 can be adjusted according to actual application conditions to obtain air guiding devices 100 with different shapes. Furthermore, the air guiding device 100 in this embodiment is a hollow structure; in other embodiments, the air guiding device 100 can also adopt a solid structure according to actual application conditions.

[0051] Furthermore, in order to further improve the air guiding effect of the air guiding device 100, in this embodiment, the first mating surface 213 is connected to the lower end of the air outlet of the air outlet channel 211, and the second mating surface 215 is connected to the upper end of the air outlet.

[0052] In this embodiment, when the first air guide surface 110 is in contact with the first mating surface 213, the end of the second air guide surface 130 near the air outlet is flush with the end face of the air outlet. The second air guide surface 130 can completely guide hot air out of the air outlet channel 211 without being blocked by the lower side wall of the air outlet channel 211. When the second air guide surface 130 is in contact with the second mating surface 215, the end of the first air guide surface 110 near the air outlet is flush with the end face of the air outlet. The first air guide surface 110 can completely guide cold air out of the air outlet channel 211 without being blocked by the upper side wall of the air outlet channel 211.

[0053] In other embodiments, the dimensions of the first air guide surface 110, the first mating surface 213, the second air guide surface 130, and the second mating surface 215 can be adjusted according to actual application conditions to improve the air guiding effect of the air guiding device 100 in cooling or heating modes. For example, the length of the air guiding device 100 can be increased, that is, the length of the first air guide surface 110 and the second air guide surface 130 can be increased to ensure that when the first air guide surface 110 is in contact with the first mating surface 213 or when the second air guide surface 130 is in contact with the second mating surface 215, the first air guide surface 110 and the second air guide surface 130 each extend out of the air outlet at one end. This is equivalent to the air guiding device 100 partially extending out of the air outlet in both heating and cooling modes, further ensuring that the air outlet of the air outlet channel 211 is completely directed out of the air outlet and preventing the air outlet from being blocked by the upper and lower side walls of the air outlet channel 211.

[0054] It is understood that the air conditioner 200 provided in this embodiment also includes a driving component, which is disposed on the body 210 and connected to the air guide device 100, and is used to drive the air guide device 100 to move within the air outlet duct 211.

[0055] In summary, the air conditioner 200 provided in this embodiment has an air guide device 100 that can move within the air outlet duct 211 of the unit 210. The structure of the air outlet duct 211 changes according to the operating mode of the air conditioner 200, achieving downward airflow in heating mode and upward airflow in cooling mode. Furthermore, compared to traditional air conditioners with air guide plates, this does not obstruct the airflow of the air conditioner 200, significantly reducing airflow loss and thus significantly improving the energy efficiency of the air conditioner 200.

[0056] Therefore, the air guiding device 100 provided by the present invention can reduce the air volume loss of the air conditioner 200 and improve the user experience while meeting the air guiding requirements. The air conditioner 200 equipped with the air guiding device 100 provided by the present invention has the characteristics of low air volume loss and better user experience.

[0057] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
